1. Lack of social interaction – As children grow older it becomes important for them to interact with other children. This socialization prepares them for school. Without it, they may have a more difficult time adjusting.
2. Bored kids – Since the kids are home all the time there is more of a chance they will become bored with the same routines. Unless your nanny is unusually creative and resourceful it may be difficult for her to keep the kids adequately entertained day after day.
3. Wear and tear on the home – There will be constant activity in a home with a nanny and the children there all day. This will add more to the housekeeping chores than if the children were being cared for elsewhere.
4. Additional costs – Hiring a nanny will generally cost more than putting your child in a day care center. Along with her salary, you will need to pay nanny taxes, possibly transportation costs and extra insurance costs for workers comp and added liability coverage.
5. Additional meals – Having a nanny means you will need to have additional groceries on hand for meals, both for the nanny and the children. This means extra meal planning and grocery costs.
6. Less privacy – Privacy issues can arise with a nanny. Constantly having another person in the house can get to be stressful if it impacts your privacy. Personal documents and information you might normal feel free to leave in the open might need to be handled with more care.
7. Less cooperative kids – Kids can become unruly just because they feel so comfortable on their own turf. When they are in the comfort of their own home sometimes they feel as if they can challenge the authority of outsiders. This can cause discipline problems for the nanny.
8. Preschool education – Your toddler will miss out on many preschool activities and the education a preschool provides by staying home all the time with a nanny. This might also affect your child’s ability to easily socialize with other children when it comes time to enter school. Group activities with other preschoolers teach little ones how to cooperate and share with one another.
9. Jealousy – The green eyed monster can come most unexpectedly to mothers when they realize their little one seems to be more attached to the nanny than Mom. Even though it may not be the case, it can certainly seem that way since the child is spending hours with the nanny instead of Mom.
10. Manipulation – Kids might feel like they can manipulate situations to their advantage by playing Mom against the nanny. Kids are pretty smart when it comes to knowing how to control things in order to get what they want.

Knowing the disadvantages of having a nanny in the home before you take that plunge can help you decide whether you want to brave those waters or not. Having a nanny may be a convenience for some parents and their busy schedules, but it does come with some costs in other areas.

1. Frustration: The biggest reason a child bites is because they are frustrated with something.  They are unable to determine another way to react to a situation so they lash out in the natural way of biting.  As a parent, try to determine what it is that is frustrating your child and help them find other ways to deal with their frustrations.  Teach them how to come to you and say that they are frustrated.  If they are non-verbal teach them the sign language for frustrated.  You can either look it up on the Internet or you can just make up something that works for you.
2. Anger: Another big reason for biting is out of anger.  Maybe another child has taken the toy they were playing with or maybe they are playing with a toy that your child wants, but doesn’t want to wait for it so they bite.  Teaching your child how to ask a child to share a toy might help.  However, at young ages this might not be possible so it might be good to make sure there are several of the most popular toys during playtime.
3. Teething: We think of this as something only babies do, but it often goes into the toddler years.  The child’s gums are hurting and it feels better when they bite or chew on something.  This is an easy one to fix.  Put a numbing agent on their gums or give them something appropriate to chew on.
4. Seeking attention: Sometimes a child is just trying to get more attention and negative attention is better than no attention.  The best way to nip this in the bud is to make sure that when the child bites to firmly correct them and then ignore them and shower attention on the child who they bit.  They will figure out that they aren’t going to get any attention when they bite and they will stop.
5. Feeling threatened: If the child feels threatened they will react like any small mammal would.  They bite and maybe scratch.  This instinct is inborn and thus very natural.  It’s not an appropriate reaction so it’s important to tell them firmly, but kindly that “We do not bite” or “Ouch, biting hurts”.  Whatever phrase you come up with it’s important to stay consistent when correcting the child.
6. Stress: I think adults tend to forget that children feel stress too.  It may be on a more basic level, but kids are very tuned into the feelings of other so that might cause them stress.  Other things that may cause a child to be stressed is being in an overly crowded area.  Maybe their environment is too loud or too hot.  All of things can cause stress for a child.  Removing the child from the stressful situation will usually cure the problem.
7. Overly tired: Sometimes children that are overly tired will lash out by biting.  They don’t know how to convey that they are tired.  Or maybe they have been rubbing their eyes and yawning, but no one is paying any attention so it’s a combination between being overly tired and being unable to communicate their needs effectively.  Making sure that a child like this gets plenty of rest should correct the biting.
8. Doesn’t like something: Some children will bite when they don’t like something.  This is a variation on just not being able to communicate their feelings in an appropriate manner.  Teaching them to say or sign that they don’t like something should clear up the biting for this reason.
9. Overwhelmed: Now this can be with almost anything.  At a young age children are unable to express their emotions and when they can’t express them they bottle them up and get overwhelmed.  Sometimes it’s related to frustrations and it’s just another form of lashing out when they don’t know what else to do.
10. Fear: Children will bite out of fear.  Sometimes children will experience fear and not be able to express it, but it will get bottled up in them.  So when they are sharing close cuddling time with their parents they will bite.  Parents are often caught totally off guard because it seems so “out of the blue”, but it’s actually the child trying to let you know that they have these feelings that they don’t know what to do with and they are ready to express them.  Give them a big hug and ask them what’s wrong.  If the child is non-verbal they may just laugh or cry, but at least they are getting the emotion out in some way.
